美国海军研究实验室的科学家们,研制了一种独特的雷达系统,用以帮助高速行驶的舰船发现在航道上的漂流物。在汹涌的海况下,漂浮物回波常被骚乱海面的其它回波所搅混,所以常规雷达发现不了漂浮的废弃物,如油鼓木料等。美国海军研究实验室新研制的这种雷达,能够区分海水回波和坚硬的漂浮废弃物的回波。这样,便可帮助舰船躲开漂流物而安全行驶。 Scientists at the U.S. Naval Research Laboratory have developed a unique radar system to help ships at high speeds find drifts in waterways. In turbulent sea conditions, the echoes of floating objects are often mixed with other echoes of the riotous sea surface, so conventional radars can not find floating wastes such as oil drums and wood. The radar, newly developed by the U.S. Naval Research Laboratory, distinguishes echoes from sea echoes and hard floating debris. In this way, you can help the ship escape the drift and safer.
